Zero weight articulating access door

ABSTRACT

A weightless articulating door mount for a gaming machine is disclosed. The weightless articulating door mount has a four link mechanism and a cam. A biasing mechanism interacts with the weightless articulating door mount through the cam and provides a uniform force counteracting the weight of the door/monitor. With the door/monitor effectively weightless, the door may be opened and will remain in place absent any further disturbance.

BACKGROUND

The subject matter of the present disclosure relates to a door mount,and more particularly, to a gaming machine having an articulating doormount with a zero effective weight door.

In the casino gaming industry, the interior of gaming machines issecured to prevent unauthorized modification, but must be accessible toallow authorized maintenance and service. An access door is typicallyprovided to allow access to each component within the gaming machine.Modern gaming machines use video monitors to interact with a game playerand provide an immersive environment. In many gaming machines themonitors are placed on the access door and are designed to be a mainpoint of entry into a gaming cabinet. As screen technologies advance,monitors sizes increase and the size and weight of the door increases aswell.

In most cases, these access doors are opened by rotating on a hingepoint. For example they may swing horizontally, or rotate verticallyfrom a top or bottom hinge. The doors typically include a conventionallinear spring push such as a strut to assist opening the access door toaccess the interior of the cabinet. The linear spring may hold the dooropen if it is of sufficient size. However, as monitors and theirrespective access doors on which they are mounted grow in size, theability to lift and pivot the loaded access door is becoming moredifficult, requiring larger struts. Additionally, gaming machines becomeprone to tipping as the additional moving weight of the monitor swingsaway from the gaming machine.

In theexemplary embodiments, the links are secured together by the shaft of abolt passing through eyeholes in the links allowing the links to rotateabout the axis of the shaft.

Stationary link 716 is configured to be secured to cabinet 704.Stationary link 716 may be secured to cabinet 704 through bolts 722 orother conventional fasteners. Stationary link 716 may be removed fromcabinet 704 for ease in assembly and maintenance by removing bolts 722.Door link 714 is configured to be coupled to monitor 702 and moves ateach end relative to cabinet 704. Door link 714 may be a separate linksecured to monitor 702 or a door, or door link 714 may be the door ormonitor itself. For example, door link 714 could be a rigid door havingan upper tab with an eyehole and a lower tab with an eyehole forconnection to a link. Upper link 718 is rotatably coupled to door link714 through a first rotatable coupling 715 and to stationary link 716through a second rotatable coupling 717. Similarly, lower link 720 isrotatably coupled to door link 714 through a third rotatable coupling719 and to stationary link 716 through a fourth rotatable coupling 721.

Opposing links may be of equal length. For example, upper link 718 andlower link 720 may be the same length, and door link 714 and stationarylink 716 may be the same length. In such embodiments, door link 714 andstationary link 716 remain parallel throughout their movement. Thus,monitor 702 mounted to door link 714 would remain at the same angle asmonitor 702 is lifted.

Biasing mechanism 726 is configured to bias door link 714 upward.Biasing mechanism 724 may bias door link upward directly, or morecommonly through another link. For example, a torque bias on eitherupper link 718 or lower link 720 will bias door link 714. Biasingmechanism 726 may be a spring and in the exemplary embodiment is atorsion spring.

Biasing mechanism 726 interacts with cam 724 to provide a relativelyconstant bias to door link 714, such that the weight of monitor 702 issupported at each position of door link 714. Having a relativelyconstant bias results in a monitor that has the sensation of beingweightless. In the exemplary embodiment, a torsion spring biases arm 728to rotate about torsion spring. Arm 728 contacts cam 726 and biases cam724. Because cam 724 is coupled to lower link 720, contact with the arm728 provides a torque bias to lower link 720 which then biases door link714 upward.

The torsion spring is advantageous in that it may have a relativelyconstant force when compressed. A conventional spring, such as a linearspring requires a linearly increasing force to compress it. As a result,a door biased by a linear spring may have a bias force much greater thanthe weight of the door and monitor when it is compressed, causing themto lift or spring when the door is opened. A torsion spring, incomparison, may have a relatively constant torque throughout its rangeof motion putting a uniform pressure on the linkage. The force needed tolift the door is therefore relatively constant. By reducing theeffective weight of the monitor door, an operator may open and close thedoor without having to overcome an additional force need to keep thedoor open.

In some embodiments, biasing mechanism 726 is made from several smallrods in torsion. The spring rate of the biasing mechanism 726 isdetermined by the number and size of the small rods. If there is afailure in a rod of the biasing mechanism 726, the spring rate is onlyreduced by a small percent preventing monitor 702 from fully closing.This protects the operator from being injured from a falling monitor 702in any position. One benefit of using a biasing mechanism 726 to givezero weight to monitor 702 is that all required variables are constant,so the operation life of the cabinet door can be calculated withoutaddition inputs like shelf life, opposing force and environmentalfactors. By determining the operation life, the cabinet door can have adetermined replacement schedule past the operation life of the cabinetmaking the door operation service free.

Linkage assembly 712 prevents monitor 702 from swinging out excessivelywhile maintaining monitor 702 in an upright position during movement. Ascan be seen in a comparison of FIG. 10 and FIG. 12, when monitor 702 israised to its maximum vertical extent, its horizontal displacement isminimal compared to a conventional swinging door.

Cam 724 may be a separate component mounted to a link, or in someembodiments cam 724 may be integrally formed with a link. For instance,in the exemplary embodiment, cam 724 and lower link 720 are a singlepiece. Cam 724 provides a smooth transition surface biasing mechanism726 apply its bias. Biasing mechanism 726 pushes cam 724 with enoughforce to counteract the weight of monitor 702 and linkage assembly 712allowing monitor 702 to become effectively weightless. Because monitor702 is essentially weightless, monitor 702 remains in any position atwhich it is left. For example, if a user moves it halfway up, it remainshalfway up absent any further force.

FIG. 14 through FIG. 16 are side views of articulating door mount 710and illustrate the operation of biasing mechanism 726 and cam 724. FIG.14 illustrates articulating door mount 710 in a closed position, FIG. 15illustrates articulating door mount 710 in a mid-position, and FIG. 16illustrates articulating door mount 710 in an open position. In each ofthese positions, cam 724 and biasing mechanism 726 cooperate to providea relatively constant upward force balancing the weight of monitor 702.The force exerted by biasing mechanism 726 is related to the effectiveradius of cam 724. When cam 724 has a low effective radius, there islittle relative preload on biasing mechanism 726 and the bias isminimal. When cam 724 has a higher effective radius, the preload ofbiasing mechanism 726 increases and the bias force is increased.

In FIG. 14, the weight of monitor 702 is nearly tangential to the lowerlink 720, and a minimal amount of torque is required to counteract theweight of the monitor 702. In this position, cam 724 has a minimumeffective radius and provides little pre-load to biasing mechanism 726.In FIG. 15, the weight of monitor 702 is perpendicular to lower link 720and the greatest amount of torque is required to balance the weight ofmonitor 702. In this position, cam 724 has a greater effective radiuspre-loading biasing mechanism 726. This in turn results in a greaterforce being applied to the lower link 720, balancing the weight ofmonitor 702. In FIG. 16, monitor 702 is at its maximum height. Theweight of monitor 702 is again nearly tangential to the lower link 720and less preload is required from biasing mechanism 726 to supportmonitor 702. Thus cam 724 has a lower effective radius in this position.Additionally, cam 724 includes a stop 728 preventing monitor 702 frombeing over extended.

Monitors of varying weight may be supported using the described system.Different weights will require biasing mechanisms having differentspring constants. For example, a lighter monitor may be supported byremoving some of the rods from the torsion spring, while a heaviermonitor may be supported by adding rods to the torsion spring. Becausethe range of motion would not change, the cam may be reused in suchembodiments. If a different biasing mechanism were used, or if thegeometry of the linkage assemblies were changed, it may be necessary touse a different cam shape. In general, in areas requiring a greaterbias, the cam has a greater radius to preload the biasing mechanism,while in areas requiring lower bias; the cam has a reduced radius.
